yes, you can bitblt from the desktop to your window 🤷‍♂️

#

just bitblt from screendc to memdc 🤷‍♂️

#

why would you do it in WM_CREATE?

#

in general, you only get to paint the window when WM_PAINT is called

#

screenrecorders almost certainly don't use GDI at all

#

way not fast enough

#

they will use the dxgi desktop duplication api

#

#
